The latest round of repairs, rebuild and upgrades have been completed enough to start the stroked 383ci Cleveland motor. We needed to check all the lines for the new steering and engine oil cooler, etc, check the fuel lines, rail, etc.
It went really well except for the small surprise of a fire! But it was only a sticker on the new exhaust burning off, and the smoke was mostly from the high-temp engine paint.

Our 1973 Mach 1 Mustang finally made it on the dyno. We tuned it and ran it with the crappy intake manifold, then put the Edelbrock Air Gap manifold on and ran it again. No loss of HP with the dual plane, and huge gains in torque.
We finished up with 313kw/420hp and 608nm torque. The power comes in nice and early, with a big fat curve. We have 200kw (rear wheel) and a boatload of torque at 3600rpm, and doesn't drop back down to 200kw until 5800rpm - the perfect curve for our Tarmac Rally.
So now the cam is holding us back. We need bigger lift and more duration. Our cam was great for a 351ci Cleveland, but too small for our 383ci. We will consider that after Targa Wrest Point in January 2011, our next race.
